For those who pre-ordered from other retail outlets, those locations are also expected to receive limited supply and hopefully begin shipments simultaneously. Needless to say, there still looks to be higher demand than availability. The eBay pricing of $100 for these $30-$40 adapters is a tell tale sign. Do not expect the supply to be available on store shelves for several more weeks, or longer.

UPDATE 1/24/2011: Mad Catz has updated their Rock Band forum post, stating all Amazon pre-orders will be filled this week.

Are you getting this for your drum kit to replace the GH one? Also have you decided on whether or not you’re getting the Fender when it’s available? I’m definitely grabbing that but likely not in the first wave of orders.

I plan on using the MIDI PRO adapter to replace my GH:World Tour MIDI capable kit. With the replacement, I will get: (1) RB3 Pro Mode enabled, (2) more free space in my living room, (3) easier navigation having the controller mounted on my Roland kit.

I will definitely get the Fender, but like you opted not to pre-order. I’m going to wait for the 2nd generation, which will give me time to get my Pro Drums stats and Pro Keys stats up on the leaderboards.
